How to calculate Tetenal's Beta?greenspun.com : LUSENET : B&W Photo - Film & Processing : One Thread |
Ilford uses G. Kodak uses CI. Tetenal uses Beta. I have the info on Ilford and Kodak but how do I calculate Tetenal's Beta? They have some really nice data sheets but I need to know what I should measure... thanks
